STEAMI SHOVEL.

Application filed March 1, 1923.

To all whom it may concern:

Be it known that I, THOMAS S. HUsHEn, a citizen of the United States, residing at Roxbury. in the county of Suffolk, in the State of Massachusetts, have invented a new and useful Improvement in Steam Shovels, of which the following is a specification, reference being had to the accompanying drawings.

The present invention relates to improvements in steam shovels and the like.

t is a matter of common experience with he operators of steam shovels that much time is wasted in operating a steam shovel on account of the dipper stick being caught between the boom and hoisting cables, thus springing the dipper sticks apart and at times breaking the cables causing serious accidents and delay of time.

The present invention relates generally to improvements in means for protecting dipper sticks of steam shovels against damage result-ing from collision with the boom fall. and hoisting cables.

The primary object of my invention is to provide a device of the aforesaid character which may be cheaply manufactured and readily attached to dipper sticks without altering the construction or detracting from the appearance thereof, and which when positioned will effectively guard against injury the parts of the dipper stick which it is designed to protect.

Another object of the invention is to provide a dipper stick guard which will embody the fewest possible number of parts and of such a nature as to be particularly effective in deflecting the shocks from encountering obstacles and to have a tendency to brush the obstacle struck to one side minimizing the danger of injury either to the dipper sticks or to the object encountered.

A still further object of the invention is the provision of a guard structure which will be efficient and durable, and will not be destroyed or permanently distorted or injured by the less important shocks to which a guard is frequently subjected so that the guard will not be quickly rendered useless or distorted into unsightly form.

Serial No. 622,107.

These objects are secured by the construction and arrangement of parts as hereinafter described, the novel device being pointed out in the annexed claims. Figure 1 is a perspective view of the guard. Figure 2 is a side View illustrating the guard applied to a dipper stick.

With the above-mentioned and other ends in view, the invention consists in a novel construction, arrangement and combination of parts hereinafter described and illustrated in one of its embodiments in the accompanying drawings and particularly pointed out in the appended claims.

Referring to these figures by characters of reference, numerals 1 and 1 designate the end supporting members, 2 and 2 are projections from said supporting member. 3 and 8* body members extending upwardly as illustrated in the drawing forming an angle of degrees. The top portion of body member 8 is diverged or preferably, bent to an obtuse angle. 4 and 4 are reinforcement bars parallel to the body members. The dipper stick 5 is hollow, the end which is opened, forms a socket or cavity which receives the projections 2 and 2 The supporting member is secured and held to the dipper stick of the steam shovel by bolt 7 which passes through the projection of the supporting member. By this arrangement it will be manifest that my invention may be readily applied to dipper sticks of steam shovels of various types and positioned relatively to the parts thereof to be protected to form an efficient guard.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent is:

1. A dipper stick guard comprising a body member extending upwardly at an angle of 45 degrees and bent centrally to form oppositely divergent l extending portions, supporting members extending from said body members, means for fastening said supporting members.

2. A dipper stick guard, for extension across the ends of a dipper stick, said guard comprising a body member extending upwardly and centrally bent forming divergent portions, supporting members extending from the ends of the body members, means for fastening one end of each supporting member to an end of each dipper stick.

A guard for dipper sticks comprising a divergent body member for extension across the dipper sticks, supporting means for said divergent body members, the said supporting members constituting continuation of 10 the body member.

4. A dipper stick guard comprising a body member extending upwardly and bent centrally to form oppositely divergent portions,

reinforcement longitudinal bars parallel to 15 the said body member.

THOMAS S. HUSHER.
